TRUCK AND BODY BOLSTER.

SPECIFICATION forming part of Letters Patent N 0. 738,212, dated September 8, 1903.

I Application filed December 4, 1902. Serial No. 133,857. (No model.)

1'0 all whom it may concern.-

Be it known that I, ARTHUR LIPscHUTz, a resident of the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Truck and Body Bolsters, of which the following is a specification.

My invention relates to truck and body bolsters for railr0adcars; and the object of my invention is to provide a strong all-metal bolstcr of less weight and cost than the bolsters which are now in use devised or invented heretofore.

A particular object of my invention is to provide a truck or body bolster in which ordinary rolled or structural steel shapessuch as channelbars, I-beams, and the 1ike-m ay be employed without alteration in shape.

Another object of my invention is to provide a metal bolster comprising two parallel bolster members which though ordinarily combined in a single bolster,maybe used independently, each as a light bolster.

My invention consists in a car-bolster comprising parallel rolled steel beams suitably fastened together and each having a truss comprising a solid web that is rimmed by a flange that follows the complete outline of said web, the long .flange of the truss being in each case riveted to the flange of its respective beam; and, further, my invention consistsin various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 illustrates a truck and a body bolster embodying my invention. Fig. 2 is a cross-section of the body-bolster. Fig. 3 is a similar view illustrating a modification of the invention. Fig. 4. is a further cross-section of my bolster, showing I- beams in place of channel-mains; and Fig. 5 is a perspective vicwof one of the individualtrusses comprising my invention.

The most practical form of my invention includes a rolled channel 2 or a rolled I-beam 3, these being commercial shapes which can be readily obtained in various sizes as required in the manufacture of bolsters for cars of different carrying capacities; but other and different beams and shapes may be utilized within the scope of my invention, though not eco nomically adapted to bolster construction. The gist of this invention resides in a pressedsteel individual truss having a continuous flange or rim riveted to the flange of each beam.

The simple bolster element of my invention comprises a rolled channel 2 or a rolled I-beam 3 and a shorter truss at, that is riveted to the lower flange of the beam, with its web a in alinement with the web of the beamthat is, in the same vertical plane. The truss comprises said web 4. and the continuous flange or rim 4", the longest straight portion or side of which is applied to the flange of the beam.

As shown, the flange or rim of the truss conforms to or outlines the truss, which, as shown, isof varying depth and is provided with a flat bottom 4!, that is a portion of the flange l"; In the case of a body-bolster the center plate is attached to said flat portion 4'. This simple bolster element, as pointed out in a companion divisional application, is suitable for employment as a bodybolster fora light car and when equipped With column-guides, such as 5, is a very good truckbolster for such a car, presenting a maximum of strength in a minimum weight of material. The ordinary demand is for a heavier bolster, which I make by placing two of the described elements orsimple bolsters back to back and securing the same by means such as the diaphragm-blocks 6 and the end straps 7, which may be of various designs and arrangements. This bolster may be strengthened by the addition of a cover-plate S and may be further strengthened by an intermediate plate 9, fastened between the beam and their trusses. A still heavier bolster is made with I-beams in place of the channel-beams. The truckcenter 10 may be attached to the top of the truck-bolster and the center 11 to the bottoms of the trusses of the body-bolster in anysuitable manner.

' It is obvious that numerous modifications of my invention will readily suggest themselves to one skilled in the art, and I there* fore do not confine the invention to the specific constructions herein shown and described.

Having thus described my invention, I claim as nea and desire to secure by Letters Patent- 1. The bolster, comprising the parallel flanged beams, rigidly secured together and each provided with an individual pressedsteel truss, riveted to its lower flange and comprising a vertical Web having a continuous flange or rim, substantially as described.

2. The bolster, comprising the parallel rolled-steel beams, having lateral flanges, in combination,with means rigidly securing said beams together, and, the individual trusses of said beams, each comprising a Web of varying depth having a continuous flange or rim, the upperportions of said trusses being riveted ARTHUR LIPSCHUTZ.
